摘要： Immediately after firmware is installed in a flash ROM (R2), a CPU (C2) erases adjustment value information required for recording in the flash ROM (R2) in response to a command (3), for example, so that in an optical disk device serving as a removable medium recording/reproducing device, the CPU (C2) cannot receive a command relating to recording, thereby inhibiting the recording function.

摘要： An optical disc wherein recording can be performed on a label plane even only by an optical disc recording/reproducing device using a direct-current motor as a power supply of an optical pickup in a traverse direction. The optical disc is provided with a visible information recording layer (207), which can record visible information by changing a physical structure by irradiation light of the optical pickup, and a radius position information recording part (201). Therefore, even when an optical disc recording/reproducing device using a direct-current motor as a power supply of the optical pickup in the traverse direction, the contents of the radius position information recording part (201) are read and recorded on the label plane only by the device.

摘要： The direction in which an information disk apparatus is installed is judged without employing a sensor means. A control means (116) measures the number of track crossings when a reading means (104) is moved by a driving means (109) in a direction corresponding to the radius of an optical disk (102) for a predetermined period of time, and judges a direction in which a DVD-ROM player (101) is installed on the basis of the measured number of track crossings.

摘要： The present invention provides an information disc recording/playback apparatus which includes a track cross detection means (112), a track cross direction detection means (113), a rotation angle detection means (114), and a count means (115), detects the track pitch of a disc, evaluates the vibration amount, or vibration speed, or vibration acceleration considering the track pitch of the disc, and determines a maximum rotation speed that is lower than the allowable vibration amplitude, vibration speed, or vibration acceleration of the information disc recording/playback apparatus; as well as a vibration detection method for the information disc recording/playback apparatus. This information disc recording/playback apparatus can perform vibration detection using a single threshold value that is independent of the type of the disc, without using an acceleration sensor, and further, the apparatus can accurately perform vibration detection even when direction detection is difficult.

摘要： Information about the number of traversed tracks is acquired with a code at a first rotational speed and a second rotational speed in each area provided by dividing one rotation into m (m is a natural number equal to or larger than 1). As to the information about the number of traversed tracks, a difference is calculated between the areas. A value proportionate to the sum of absolute values of the information about the traversed tracks in the areas is used as a vibration detection value proportionate to vibration amplitude.
